were added for each intake of fallout materini. Step 1. Determine the Sr°9 to reach the bone. According to reference 4; The Sr”89 content in mixed fission products on the 120th hour is 1.64%. According to reference 5: The intake of gr°? to reach to the bones is 25%. Therefore: (27) (0.016)(0.25) = 0.108, to the bone. Step 2. Determine the dose rate to the bones. With an assumed effective energy of 0.55 Mev (reference 5). (0.108) (2.2 x 10°) (60 x 24)(1.6 x 10°) (0.55) =4.3x 107+ rads/day (100) (7,000) or 0.43 millirads/day Step 3. Determine total dose. D total =R Ae where: D total = 0.43 0.0133 RF ® initial dose rate Ae = effective decay constant & 32 millirads IV. Discussion DOE ARCHIVES A. Solubility The solubility of fallout material varies, depending among other factors upon the surface over which the detonation occurred. The fallout material collected in soil samples at the Nevada Test Site has been quite insoluble, i.e. only a few percent in distilled water and roughly 20-30 percent in 0.1 N HCI. However, it would be expected that the activity actually present in -7- /¥o I
